Google posted details about how reconsideration requests work on the Google Poland blog. And Google's Karolina Kruszynska confirmed with me this morning that Google went after two different Polish link networks. She tweeted:

Bartosz Góralewicz posted a picture on Twitter of these manual actions:

Here is that picture:

Bartosz believes Google did not target specifically two link networks but rather it was more wide spread and hit other networks as well. He said that "thousands of manual penalties" went out adding, "Googlers don't really know which network is which, It wasn't too severe and spread across all the major networks."

He also told me that he believes the link networks targeted include Statlink.pl, Gotlink.pl, e-weblink.com and seopilot.pl. Google has not confirmed which networks were targeted in this manual action.

Google also targeted a link network in Poland back in February of this year.
